Introduction

Advanced Adaptive Media Player (AAMP) is an application which uses gstreamer (AAMP) to present clear/encrypted HTTP Live Streams.(HLS)

HLS is a Media Streaming Protocol used for delivering visual and audio media over the internet. HLS uses the HTTP protocol and hence users can stream media from their regular web server. To Stream HLS data,source files are encoded at different data rates and will be split into chunks with the .ts file extension  and  manifest file  .M3U8  file is created  for maintaining index for the video chunks. For example, M3U8 file may give references to online files for an internet radio station. M3U8(MP3 URL that uses  UTF-8-encoding)is a computer file format for a multimedia playlist.Although originally designed for audio files, such as MP3, it is now used to point  both audio and video sources
